My mistake for not replying to you directly, but would kindly explain this to me then?
I just picked 2 random ones, but it's full of published titles, even months old, that gets featured in the most recent because they just got approved (The last updated field clearly reflects the changes needed behind the scenes done by the staff to enable indexing and visibility in the storefront)
Which, btw, totally makes sense to me. If this is a bug, it's so wide-spread it basicaly turned itself into a feature.
